To all wk m it may concern:

Be' it known that I, 'WILLIAM LARSON, a citizen of the United States,residing at Bonner, in the. county of Missoula and State have invented anew and useful Lumber-Piling Machine, of which the following is aspecification.

he invention relates to improvements in lumber piling machines.

The object of the present invention is'to improve the construction oflumber piling machines, and to provide a simple and comparativelyinexpensive portable machine, designed for handling both lumber andother heavy material, such as logs, rails, timbers and the like, andcapable of enabling, the same to be readily transferred from a wagon toa stack and vice versa', and adapted to be for loading and unloadingcars, boats and various other vehicles.

A further object of the invention is to provide an extensible lumberpiling machine of this character, adapted to be varied in length toarrange it for handling different kinds or lengths of material.

With these and other objects in view, the the construction and partshereinafter fully described, illustrated in the accompanying drawings,and ointed out in the claims hereto appended it being understood thatvarious changes in the form, proportion, size and minor details ofconstruction, within the scope of the claims, may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the drawings Fi ure 1 is a side elevation of a lumber pi ing machine,constructed in accordance with this invention. Fig. 2 is a transversesectional view onjthe sectional view on the line 33 of Fig. 1. Fig. 4 isa detail sectional view, illustrating the manner of slidably mountingthe rear adjustable upright frame onthe wheeled supporting frame. Fig. 5is a detail view, illustrating the manner of mounting the centraltopshaft.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

In the accompanying drawings in which able material and 2-2 of Fig. 1.Fig. 3 is a horizontal verse bar 21 and having is illustrated thepreferred embodiment of the invention, l--designates a supporting frameequipped with front 2 and 3 mounted on front and rear axles 4 and 5. Thefront and rear axles are connected with front and rear bolsters 6 and 7,secured to one side of the horizontal supporting frame, ning gear may beemployed, and the machine is equipped with a pole ortongue 8 to enabledraftanimals to be attached to it for hauling it from one point or placeto another.

The supporting frame, which is horizontal, is composed of spaced sidesills 9 and transverse connectin bars or beams, and it has mounted on itront and rear upright frames, which taper upwardlyf The front uprightframe, which is fixed to the supand rear wheels but any other suitablerunporting frame, is composed of oppositely I inclined guiding standards10 and 11, constructed of channeledmetal, or other suitrigidly securedat their lower ends to the side sills and connected at their upper endsby a top cross piece 12.

\ The oppositely inclined standards 10 and 11, which are also connectedat their lower portions by a lower transverse bar 13, are provided attheir outer faces with longitudinal grooves or channels, located betweenthe side flanges of the standards and receiving the outer flights orstretches of oppositely inclined endless conveyer chains M and 15,arranged onupper and lower polygonal chain or sprocket wheelslfi and17'.

The channeled standards andythe endless conveyer chains are arranged indifferent transverse planes, as clearly illustrated in Figs. 1 and3 ofthe accompanying drawings,

and the upper and lower transverse connect ing bars or pieces 12 and 13are located between the transverse planes of the standards and theconveyer chains and are secured to the adjacent faces ofthe standards,the latter being located at opposite sides of the transverse connectingbars or pieces.

The rear upright frame, which is adjustable along the horizontalsupporting frame, is composed of oppositely inclined guiding standards18 and 19, connected by a top."

transverse bar or piece 20 and a lower trans their lower ends fittedagainst the outer faces of the side sills 9 of the wheeled frame andprovidedv with approximately hook-shaped lugs or flanges 22, projectinginwardly and downwardly from the rear faces of the standards 18 and 19and extending into and en-.

gaging longitudinal guide grooves 23 in the upper faces of the sidesills 9. By this con structionthe rear upright frame is slidably' Theloweruends of the standards 18 and' 19 are equipped with downwardly andinwardly extending bearing arms 28, arranged inpairs and secured to theside faces I of the standards 18 and 19 at points below the sills 9-andconsisting of inwardly extending horizontal portions and dependinginclined portions. extending downwardly and inwardly'from the horizontalportions. The horizontal portions of the bearing arms 28 extend topoints beneath the sills 9 in slightly spaced relation with the same butin close proximity thereto to prevent the hookshaped lugs or flanges 22from being accidentallyllifted out of engagement with the longitudinalgrooves I The bearing arms 28 are also located at opposite sides of thelower sprocket wheels 27, and they are adapted to slide the latter alonga pair of lower longitudinal shafts 29, provided with longitudinalgrooves 30, which are engaged by keys 31 of the lower polygonal chain orsprocket wheels 27. The shafts 29,which 3 ,are located below the side.sills of th'e'sup porting frame, are journaled in front and rearbearings 32 and 33, depending from opposite sides of the frame at thefront and back thereof, as clearlyshowir in Fig. 1 of the drawing". Thelower front endless chain or sprocket wheels 17 are keyed or otherwisesuitably fixed to the front "portions of the lower shafts 29, and theupper polygonal chain or mounted on an upperi centrally arranged shaft34, journaledin suitable bearings 35 and 36 of the top connecting 'barsof the" front and rearv upright frames. The front.

upper chain or sprocket wheels are keyed" or otherwise fixed to thefront portion of the upper shaft 34, which is provided with alongitudinal groove 37 to receive keys 38 of the upper rear chain orsprocket wheels. whereby the latter. are slidably interlocked with andare adapted to move longitudiat one side of the machine sprocket wheelsare nally of the upper shaft 34 when the rear upright frame is adjustedbackwardly or forwardly. The rear upright frame is equipped at the topwith arms 39, which, as clearly illustrated in Fig. 1 of the drawings,are spaced apart to receive the upper ,rear chain or sprocket Wheelsbetween them, and they cause the same to slide on the shaft 37 when therear upright frame is adjusted to arrange the front and rear endlessconveyer chains the proper distance apart tosuit the lumber or othermaterial operated on.

The polygonal chain or sprocket wheels are grooved to receive the linksof the chains, which are arranged between the peripheral side flangesor. walls of the grooves,

and the said wheels have straight polygonal faces 40 at the bottoms ofthe grooves corresponding with the length of the links of the conveyerchains. which form a carrier or conveyer, are'pro The conveyer chains,

vided at intervals with angularly disposed projections or arms 41inclined upwardly and outwardly while traveling at theouter flights ofthe endless conveyer chains, and adapted to support pieces 42 similarmaterial to convey the same upward and downwardly at the opposite sidefor loading and unload ing material either to convey the same from cars,boats, etc, to wagons or for transferring the material from wagonsto alumber pile or stack. The outer flights of the conveyer chains at oneside of the machine travel upwardly while the outer flights of theeonvever chains at the other side of the machine travel downwardly andthe arms are at a position so that'whcn the arms at one side of themachine carry the'material over the top, the arms of the cha-ins.attheopposite side of the machine will be in positiori 'to receive thematerial. -'l?he ,ch ains- If Qof'the drawings and the lumber carryingarms or, progections downwardly -and outwardly are =inc'lined whiletraveling are oppositely inclined, as clearly shown-in along'the innerflights of' the conveyerf ch a ins.

The rear upright frame is braced and secured in its adjustment byoppositely inclined braces 47, composed of overlapped sections pivotedat their outer ends 48 to the upright frames and having inner overlappedportions provided with longitudinal slots 49 for the reception of bolts50, or

. other suitable fastening devices for securing the overlapped sectionsin their adjustment. The upper portions of the upright frames are alsoconnected by a horizontal brace 51,

composed of overlapped sections connected attheir outer ends to theupright frames and havinginner overlapped portions provided withlongitudinal slots 52 and secured in their adjustment by a bolt 53,arranged in the said slots 52. The inclined braces are located atopposite sides of the machine, and

the horizontal brace connects the frames at the side of the machine atwhich is arranged the inner flights of the outer endless conveyerchains. By this arrangement the upper horizontal brace is placed clearof the conveyer chains. Any other preferred arrangement of braces may,of course, be employed. The endless conveyer chains may be operated by amotor 54 of any preferred type, or. any other suitable means. The motorshaft- The upright frames are equipped at the outer sides-of theirstandards with loops 58, arranged at different elevations and adapted toreceive the hooked terminals 59 of skid bars 60 and 61. The skid bars60, which are adapted to extend downwardly at an inclination from thelower portions of the upright frames, are preferably supported at theirouter ends by legs 62, piv-,

oted at their, upper terminals to the outer portions of the skid bars 60by bolts 63, or other suitable fastening means, which will permit thelegs and the skid bars 60 to be folded when not in use. The skid bars61,

--which are arranged at an inclination, are

adapted to extend downwardly and outwardly from the loops at the lumberpile, as clearly illustrated in Fig. 2 of the drawings. loops permit anadjustment of the skid bars to enable them to rest properly on the lum-The-hook-shaped terminals and theber pile as the latter increases inheight. The arrangement of the skid bars in Fig. 2 of the drawingspermits lumber to be taken from a lumber wagon 64 and transferred to alumber pile 65. The lumber from the wagon is placed on the skid bars 60in the path of the inclined carrying arms of the conveyer chains, and iscarried upwardly at one side of the machine to the top thereof by oneset of conveyer chains and is then carried downwardly at the oppositeside of the machine by the other set of conveyer chains, which depositthe lumber autoinatically on the inclined skid bars il. The material isthen placed on' the lumber pile.

The machine is adapted for handling lumber and various other material,such as.

heavy timbers, rails and logs, and it in M constructed of any size andstrength'i-te adapt it to the character of the materialito 3 be handled.
